Genuine HP 776 Matte Black Cartridge

The HP 776 matte black ink cartridge (1XB12A) is a genuine HP supply designed for compatible HP DesignJet printers. It delivers professional matte black output for technical drawings, maps and monochrome graphics. This cartridge suits architects, engineers and print-service providers who need consistent line quality on plain and coated media.

Consistent output during long print runs

The cartridge is engineered to maintain stable ink flow and density across extended print jobs without the density drift that can appear in short-burst testing. Pigment formulation resists settling so that the first and last page of a large batch share the same optical density. Users avoid mid-job interventions and reprints caused by fading or banding on high-coverage pages.

Replaces depleted 776 matte black supplies

This item replaces an empty HP 776 matte black cartridge in printers that use the 776 ink system. The upgrade is worthwhile when the current cartridge shows clogged nozzles, colour shift or low-ink warnings that halt production. It is not for users who require photo black, additional colour channels or a different ink-series compatibility.

Questions about this item

Does the 1XB12A cartridge run hot or draw extra power when the printer operates continuously?

The cartridge itself has no moving parts or electronics that generate heat; all power draw and thermal load come from the printer, so the 1XB12A adds no measurable noise, heat or power overhead.

Which printer models accept the HP 776 1XB12A matte-black cartridge?

The 1XB12A is designed for HP DesignJet printers that use the 776 ink series; check your printer’s manual or the HP compatibility list to confirm it accepts 776 matte-black cartridges.

Can I mix the 1XB12A with older HP ink cartridges still installed in my DesignJet?

HP recommends using only current 776-series cartridges together; mixing the 1XB12A with earlier ink generations may trigger supply errors or affect print quality.
